To all whom t may concern:

Be it known that l, WALTER SCOTT Don, a citizen of the United States,and a resident of Kent, in the county of Portage and State of Ohio haveinvented a new and Improved PenciLharpener, of which the following is afull, clear, and exact description. i

The object ofthe invention is to provide a new and improved pencilSharpener, which is simple and durable in construction, cheap tomanufacture and arranged to permit quick and convenient sharpening ofpencils of various shapes and cross section with a view to producepointed portions of any desired length. lin order to produce the desiredresult, use is made of a plate provided at the sides with guideways, acutting blade attached to the said plate and extending across the platewith the cutting edge inward and spaced from the forward edge of theplate, the cutting edge being located in a horizontal plane extendingabove the top face of the plate, and an abutment member slidablelengthwise in the said guideways on top of the plate, the forward end ofthe abutment member `being spaced from the cutting edge of thev cuttinglblade.

A practical embodiment of the invention is represented in theaccompanying drawings forming a part of this specification, in whichsimilar characters of reference indicate corresponding parts in all theviews.

Fig. l is a plan view of the cutting blade; Fig. 5 is a side elevationof the abutment Fig.` 6 is an inverted plan view of the 1 same; 'andFig. 7 is a perspective view of the sharpener for sharpening the cuttingblade.

The Vbody of the pencil Sharpener/1s 1n the form of a plate 10 providedat its forward end with a cut-out portion 11 and provided at the sideswith upwardly and in Specification of Letters Patent.

wardly turned flanges 12 forming guideways 13 on top of the plate 10 atthe sides thereof. A cutting blade 14: extends across the plate 10within thecut-out portion 11 and the cutting edge 15 of the cuttingblade 14 extends inward and is spaced from the back wall 1G of thecut-out portion 11. By reference to Fig. 2 it will be noticed that thecutting edge 15 is in a horizontal planea short distance above the topface of the plate 10. The cutting blade 14 is provided with integralside arms 17 extending in the guideways 13 and the rear ends of the sidearms 17 are provided with apertures 18 in register with correspondingapertures 19 formed in the plate 10 and its flanges 12. The registeringaper-A tures 18 and 19 are engaged by eyes 20 formed on the ends of aU-shaped loop 21 used for suspending the pencil Sharpener from asuitable support. The eyes 20 also serve to hold the side arms 17 of thecutting blade 14: locked in position in the guideways 13 thus preventinglongitudinal movement of the cutting blade 14 relative to the plate 10.

The end of the pencil to be sharpened is abutted against the forward end24 of an abutment member 25 preferablymade in box shape and having itssides provided with flanges 26 slidably engaging the guideways 13 topermit of adjusting the abutment memberv lengthwise on top of the plate10 according to the length of the point to be given to the pencil, aswill be readily understood by reference to Fig. 2. The bottom of theabutment member 254 is in the form of a spring tongue 27 bearing on theLipper face of the plate 10 so as to hold the abutment member 25 in theposition in which it is moved by the user of the pencil Sharpener. Inorder to permit convenient sliding of the abutment member 25 toward orfrom the cutting edge 15 of the cutting blade 14E, the top of theabutment member 25 is preferably provided with a roughened portion 28which affords a firm finger hold to allow the user to move the abutmentmember forward or backward on top of the plate 10.

In order to enable the user of the pencil Sharpener to convenientlysharpen the cutting edgel whenever it becomes dull use is made of asharpener 30 removably held in the box-shapedabutment member 25. TheSharpener 30 consists of a lback Lplate 3l, preferably made of zinc orother metal, and Qn the top of this back plate 31 is placed a vpiece32'of wood'or other material "having a top surfaceof an abradingmaterial such as graphite, sand, corundum or the ,like

The abrading piece 32 is held in place 0n -thev .bacl vplate 3l .byhaving theends 33 of thelatter crimped 'over onto the top of the piece32, as plainly indicated-inliligsnand 7. The sharpening member 30 issomewhat Vionger than'the abutment member 25xsothat fthe Sharpenerextends a distancel beyond `vthe `rea-r -endof ythe abutment member'i 25yto -permit Lthe :user -to conveniently :remove the Sharpener ffl-'om:the yabutment member s25 -Whenever '\it 4is desired Ito fsharpen -thecutftinge'dge 15 `and Ato Ipermit the user ltov con- -veniently replacer`the Sharpener in `the -abut- =ment frneniberQ when the Sharpener isnot -end of thelpencil'to be sharpened is placed 1ron top ofthe cuttingblade lflwithithefter- "minal vof the :pencil ini'eontact with i' the-foriin' use.
